Benno performed a simple test at home and placed his car keys next to his bike lock. Anytime he left his house he had to choose between the two and if he picked up the car keys he had to justify why he was choosing to drive rather than ride his bike. This is how he discovered a list of objections that lead people to choose driving over cycling. The Boost is the bike Benno designed to overcome common objections to using our bikes more often.
Take a ride on this Bosch equipped electric bike and you’ll understand why “too hilly”, “too far”, “I don’t want to get sweaty” and “I can’t carry enough” are no longer good reasons to leave your bike at home. The Boost will have you looking for excuses to go on additional errands.
This compact and extremely sturdy e-utility bike makes transportation fun and easy. It’s designed to carry heavy loads and has an interchangeable rack system that you can pick and choose from to fit your needs. The strong frame and big tires are the perfect pairing for the powerful Bosch motor.
People describe the feeling of riding with Bosch’s leading e-bike mid-drive system like suddenly having super-powers. Benno likes to call it the Boost.

The Big Fat Dummy is a long tail cargo bike that took a few too many doses of growth hormones. At first glance, you might say that Surly just put bigger tires on a Big Dummy. But if you said that, you'd actually be very wrong so just… don't. Think of Big Fat Dummy as more of a second or third cousin to Big Dummy rather than a brother. They share some of the same DNA and look sort of similar, but they're two very different bikes and really only interact when they both reach for the potato salad spoon at that family reunion that no one really wants to be at anyway.
Now that that's out of the way, let's get down to the nitty gritty of what makes this hulking beast of a bike tick. Surly's goal with designing a cargo bike around fat tires was to create the most stable, stiff, and traction-laden ride possible while hauling a ton of stuff. Big Fat Dummy has a longer toptube and slacker headtube than its more svelt cousin giving it a nice, predictable, and stable ride. They also used thinner, lighter tubing to construct its cargo area so while it's an overall burlier bike, there's not much difference in weight.
Big Fat Dummy accepts either 10mm or 12mm axles in the rear with a spacing of 190/197mm. That big ol' spacing equates to one thing: tire clearance for days. Big Fat Dummy maxes out at a massive 26 x 5.25" tire.* While that large of a tire provides the most traction and stability a bike can possibly offer, it's also a lot of rubber to push and might not be for everybody. Luckily, Big Fat Dummy is also a blast to ride with 3" tires too. It uses the same 100mm suspension-corrected fork as the Wednesday, meaning if you want to add a little squishy squishy to your ride, you can throw a Bluto on and let ‘er rip.
If you intend to carry a passenger on your Big Fat Dummy, Surly requires use of their Dummy Rail Collars. These provide a secondary retention system for the rack, as well as stiffen the rack system. In addition, a stoker handlebar set up, found on tandem bicycles, is recommended as well. Make sure to check with seat post manufacturer for stoker handlebar compatibility. All Big Fat Dummy framesets and bikes ship with a Dummy deck, rails, bags, and the aforementioned Dummy Rail Collars so you can immediately start hauling cargo — human or otherwise.
Big Fat Dummy is ready and willing to carry all sorts of crap — literally. It's already in use on an organic farm in Ecuador so it's likely that it's hauled some form of manure by now.
*Using a 26 x 5.25" tire will cause some drivetrain limitations.

The Fairfax SC6 DLX just turned your commute into the best part of your day!

Big Dummy is a long-tail cargo bike, which means that not only can you haul a serious amount of cargo, different accessories can be added to your Big Dummy frame and deck depending on what you want to carry. Being a dedicated single-piece frame, instead of an add-on to an existing bike, it's stiffer and resistant to torsional flex, which provides a better ride and longer lasting frame than long-tail add-ons.
Like all Surly's frames, it's made of their size specific, 4130 CroMoly steel – a tube set engineered for cargo that sports lots of little touches that you've come to love in a Surly, like clearance for big tires and the use of common component sizes. Figure on being able to carry about 200 pounds (90kg) of cargo. The load weight, and how it's loaded, will affect the handling somewhat. Also, plan on using gears, especially as cargo weight increases. This may seem obvious, but as you get comfy with it, you will use your full range of gears as never before.
The parts kit is good quality, and suitable to loaded as well as unloaded riding. It's got a 3x10 drivetrain, Avid BB7 disc brakes, quality Shimano Deore hubs, and 26x2.3" Kenda Kiniption tires. They've outfitted it with Surly-designed bags, deck, rails and Dummy Rail Collars; everything you need for the majority of stuff you might carry, like groceries, shovels, bags of charcoal or mulch, guitars, lamps, mannequins, whatever. Bags, deck, rails, and rail collars are all designed to improve on previous offerings and work together to make sure your stuff is transported with safety and stability. It's an unbending interface, which when you're carrying lots of cargo, is a good thing to have. Get creative, and get hauling.
If you intend to carry a passenger on your Big Dummy, Surly requires use of their Dummy Rail Collars. These provide a secondary retention system for the rack, as well as stiffen the rack system. These are included with current Big Dummy bikes and frames, as well as available for older Big Dummy bikes and frames (compatible with all generations of Big Dummy bikes/frames). In addition, a stoker handlebar set up, found on tandem bicycles, is recommended as well. Make sure to check with seat post manufacturer for stoker handlebar compatibility.
If you are planning to carry a child on your Big Dummy, Surly recommends the use of a child seat. They've tested the Maxxi Yepp seat. Yepp makes an adaptor that allows their seat to mount onto Surly's deck. It works well with the Big Dummy. At this time other child seats are not recommended and will void your warranty. Surly is testing other options. For the most up to date compatibility/options, check http://www.surlybikes.com/safety
Note: keep in mind Big Dummy weight limits when carrying a passenger.

To brake or to disc brake? The debate isn't getting any colder and Surly decided it's best to let you choose. Straggler is bred from Surly's revered rim-brake Cross-Check and comes out a lot the same, but also a little different. Frame geometry is pretty close, and you get all the attachment provisions for racks, fenders, and bottle cages that make these bikes something more utilitarian than a standard 'cross racer. Disc brakes are the obvious change though, and the Straggler sports Hayes CX Experts with 160mm rotors front and rear. The athletic character continues with a SRAM Apex 2x10 drivetrain, giving you a useful gear range for any type of riding you can dream up, and continues with 32-hole alloy Alex XD-E Lite rims wrapped in Surly's own super-versatile 700c x 41 Knard rubber. A Salsa Cowbell handlebar is great for riding on mixed terrain, too, giving you a bit more control when it's loose while retaining comfortable positioning for cranking into the wind. Make it your gravel explorer on weekends, your trusty commuter during the week, and go collect all the hand-ups when cyclocross season rolls around. This Straggler's lookin' for a good time and you seem like the type to oblige.

So what is this Straggler anyway? The easy answer is to say that Surly added disc brakes to a Cross-Check and this is close to accurate. People have asked them to make a disc version of their highly versatile Cross-Check for a long time now and almost everything about the two are very similar. Straggler is slightly different, though.
The most obvious difference of course is that the Straggler has disc caliper mounts instead of rim brake studs. It'll accept rotors up to 160mm. The rear dropouts are unique, too. They're a partially closed horizontal design that accommodates singlespeed or geared drivetrains. They feature stop screws that thread in from the rear to further secure the wheel and to position the rear wheel for optimal shifting, plus a forward-mounted stop screw on the drive side to keep the wheel from slipping forward under the force of your gargantuan legs. The rear dropouts are spaced 135mm instead of 132.5mm like the Cross-Check simply because there are far more options for disc hubs in this spacing.
Straggler shares all of the Cross-Check's braze-ons for fenders, racks and bottle cages. The Straggler's geometry is slightly different, with angles and tube lengths very close but not identical to the Cross-Check, but like the Cross-Check it's ready to take you just about anywhere. It's a day tripper and a weekender. It's a 'rough road' road bike. It's a cyclocross bike with no pretense about racing. It's a utilitarian townie. It's a light-duty touring bike. It's an all-weather commuter. And when you get tired of one set up, you can swap parts around and turn it into something else. We think that's pretty neat.
- Fender eyelets at the dropouts, front and rear rack bosses and dual water bottle mounts, downtube shifter mounts
- 100% Surly proprietary 4130 chromoly tubing. TIG-welded, double-butted main triangle
- Forward-exiting horizontal dropouts with adjusters give you singlespeed compatibility and wheelbase adjustability to help you fit the tires and fenders you want to run with that drivetrain you want to run.
- Frame is ED Coated for increased life expectancy

650b what? In the old days when randonneuring bikes ruled on long rides over mixed surfaces, the 650b tire size was perfectly suited for moving fast under control. Surly took this concept and applied it to the Straggler, a disc brake-equipped any-road type of bike bred from their revered Cross Check. The slightly smaller wheels accommodate smaller frame sizes and plump tire widths, creating options where few exist in this realm of bike riding. Disc brakes highlight the Straggler 650b story, sporting Hayes CX Experts with 160mm rotors front and rear. The athletic character continues with a SRAM Apex 2x10 drivetrain, giving you a useful gear range for any type of riding you can dream up, and continues with 32-hole alloy Alex Adventurer 2 rims wrapped in Surly's own super-versatile 650b x 41 Knard rubber. A Salsa Cowbell handlebar is great for riding on mixed terrain, too, giving you a bit more control when it's loose while retaining comfortable positioning for cranking into the wind. Make it your gravel explorer on weekends, your trusty commuter during the week, and go collect all the hand-ups when cyclocross season rolls around. This Straggler's lookin' for a good time and you seem like the type to oblige.

We think by now, most of you get what Straggler is. It's a madly versatile bike that can be used for most types of riding and riding surfaces. Better still is that you now have the option of 650b wheel size. 650b wheels were popular for a long time many years ago on 'Constructeur' style bicycles and we all know how real things were back in the day…650b wheels strike a nice balance between the benefits of both 26" and 700c sizes. The smaller wheel allows smaller riders to fit well on smaller frames, produces a stronger wheel, makes fitting big-ass tires easier and are more agile than their larger counterparts.

Benno loved the idea of inspiring people to use their bikes to carry loads — from grocery runs and hauling chairs and a cooler to the beach to dropping off oversized packages at the post office. But looking at most cargo bikes, they wondered if they really had to be so long, cumbersome and hard to store. It seems like a big commitment to ride around on one of those with all the welded on racks and extensions. Do you really need a bike that big to carry a little more?
Instead of making a cargo bike smaller, they decided to make a regular bike slightly longer and stick with a tried-and-true attachable (and interchangeable) rack system. These racks are larger, made of stronger, oversized tubing and attached with extra-large bolts. The front tray is mounted directly to the frame so your steering won’t be affected, even when fully loaded.
The Carry On is a clean utility bike that will carry a baby seat and 4 large grocery bags, or all the gear you need for a fun beach day or a camping trip. The different rack options let you pick your own configuration, while the 24” wheels keep your center of gravity low. You might be wondering why the tires are so wide. Have you ever seen a truck with skinny tires?
